Programming OCM in Standalone Configuration
4.15.2 Full-Custom Configuration
In full-custom configuration the OCM executes a firmware program running from external ROM.
This is illustrated in Figure 26B. A parallel port with separate address and data busses is available
for this purpose. This port connects directly to standard, commercially available ROM or
programmable Flash ROM devices. Normally 64KB or 128KB of ROM is required.
Both instructions and data are fetched from external ROM on a cycle-by-cycle basis. The speed
of the accesses on the parallel port is determined by the gm5115/25 internal OCM_CLK. This in
turn determines the speed of the external ROM device. For example, if a 14.3 MHz crystal is
being used to produce TCLK, and the OCM_CLK is derived from TCLK, then a 45ns ROM can
be used.
To program gm5115/25 in full-custom configuration the content of the external ROM is
generated using Genesis software development tools G-Wizard and OSD-Workbench. This is
illustrated in Figure 28. G-Wizard is a GUI-based tool for capturing system information such as
panel timing, support modes, system configuration, etc. OSD-Workbench is a GUI based tool for
defining OSD menus and functionality.
